THE IRON INDUSTRY.
coke is imported from Belgium by plants in Luxemburg, but the German article is far superior. There are three steel works in Loth-ringen and two in Luxemburg having twenty-six converters from ten to twenty tons capacity. There were only two open-hearth furnaces, one acid and one basic. All the converters are basic.
Three new plants were started in the year 1900, at Kombach, Kneuttingen and Differdingen. In Fig. XXIV-C will be found a drawing of the first of these. It is representative of the best German practice and was started in 1900. The engineer is Bergassessor Oswald, of Coblenz, to whom I am indebted for the drawings. There are seven blast furnaces in the Kombach plant, three of them new, the latter being 90 feet by S3 feet with a 13-foot hearth. It is intended to eventually use gas engines for blowing, and save the steam for the reversing rolling mills. To this end the boiler capacity is large, the pressure being 140 pounds and economizers and superheaters installed. There are two mixers each of 200 tons, feeding 4 basic 17-ton converters. The pig-iron runs from 1.5 to 2.0 per cent, phosphorus and 0.5 per cent, manganese, this latter element being obtained from ores from Spain, the Caucasus and from the Lahn district. The mixture is self-fluxing and runs about
